The ruling on one who hunts before intending to enter the state of ihram

A man entered the state of ihram from his city on his way to the miqat, and he hunted and killed game, but he did not form the intention until he reached the miqat. He only wore the clothes of ihram on the way, and then he hunted and caught game?
Entering the state of ihram is the intention. Therefore, as long as he has not formed the intention, even though he is wearing the clothes of ihram, there is no prohibition on him: no hunting, no perfume, no cutting of hair, no intercourse with his wife, and nothing else until he forms the intention. If he forms the intention, even in his house, he becomes one in the state of ihram.
